kern-tools: integrate ZFS speedup patch

kconf_check: store some files in tmpdir
Some file systems, like ZFS, are very slow at appending to existing
files. Due to Copy-On-Write nature, they create a new copy of a file
each time we do ">>" in a shell script. This becomes very noticeable
if shell script does lots and lots of appends, like sanitize_fragment()
function in kconf_check. On my setup, do_kernel_configcheck task takes
literally hours to complete.
To fix this issue, we can store sanitized_list and fragment_errors.txt
files on tmpfs, which is extremely fast at writing. As most distros
use tmpfs for /tmp, logical step is to use `mktemp` to create
temporary files.
After completing writing to temporary locations, we can move those two
files back to ${LOGDIR}.
Also, function 'cleanup' was added to remove temporary files in case
of abnormal exit.
With this patch, do_kernel_configcheck task completes in ~2 minutes on
my setup, which is a great improvement.
